title: Li local configurations for the trimerized state of the geometrically frustrated triangular lattice system Li(1-x)V O2 with 0 ≤ x ≤ 0.14.
abstract: The Li de-intercalation effects for the trimerized state of the geometrically frustrated triangular lattice LiV O(2) are investigated through measurements of x-ray diffraction, magnetic susceptibility and magic-angle spinning-nuclear magnetic resonance (MAS-NMR). Li(1-x)V O(2) with 0 ≤ x ≤ 0.14 obtained with a soft-chemistry synthesis is a single phase. All of the data are understood by considering that the partial substitution for V(3+) (spin-1) with V(4+) (spin-½) leads to the coexistence of the spin-singlet and spin-½ trimers.
